Spring AOP的增强处理

//正常操作
@Around("service()")
public void doAround(JoinPoint joinPoint) throws Throwable {
    // 接收到请求，记录请求内容
    ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    HttpServletRequest request = attributes.getRequest();
    // 记录下请求内容
    System.out.println("URL : " + request.getRequestURL().toString());
    System.out.println("HTTP_METHOD : " + request.getMethod());
    System.out.println("IP : " + request.getRemoteAddr());
    System.out.println("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
    System.out.println("ARGS : " + Arrays.toString(joinPoint.getArgs()));
} 

//获取annotation
@Around("@annotation(log)")
    public Object around(ProceedingJoinPoint pjp, Log log) {
        //获取注解里的值
        System.out.println("annotation around:" + log.description());
        try {
            return pjp.proceed();
        } catch (Throwable throwable) {
            throwable.printStackTrace();
            return null;
        }
    }


//获取异常
